摘要

Processes for conversion of the aromatic load and the manufacture of carboxiico aromatic acid, isophthalic acid, terephthalic acid, 2,6 - naphthalene dicarboxilico or 2,7 - naphthalene acid.Compositions and solutions of catalyst and terephthalic acid catalytic compositions for conversion of materials with the oxidised products comprising load aromatic acid derivatives carboxilicos aromatic materials of aromatic substituted comprise P load At least two metal or metalloid elements, one of which at least is palladium, platinum.Vanadium or titanium and one of which at least is a metal or metalloid of groups 5, 6, 14 and 15. A process for oxidizing aromatic material comprises contacting the material load following loading with oxygen in the presence of this catalytic composition in a mixture of liquid reaction.
